Once again I saw many different fish. Some old and some new. The new ones that I saw were probably there before, I just couldn't see or find them before. I also saw that my previous observation was some what accurate. The fishes do stay in certain areas. Like the big koi were near the center, the smaller fish, they were orange/yellow colored and also black/grey/strip, hung around the edge of the pond.
I also saw that there were certain routes that the fish took. They started from the chapel, hung to the edges and headed down towards the island, went around the outer side of the island, then the other side, and headed back toward the chapel. It could be that this was just for that day, they could have many different routes.
An experiment i did was isolating three fish in the same bowl. i did not feed them, they had to eat algae or find food in the bowl. The algae could be found on the walls of the bowl, or one of the three rock that were also put in there. Other alternative foods could have been one of seventeen plants put into the bowl.
The bowl was sealed up (with all of the above mentioned) and left alone for a few weeks. i wanted to see if the fishes could self sustain themselves with a supply of oxygen (the plants) and food (plants/algae).
I measured the dissolved oxygen, the pH levels, and the temperature periodically. these are the results that i came with
day 1 day 2 day 3 day 4 day 5 day 6Dissolved oxygen 7.8 6.9 2.9 3.5 5.3 5.2
pH level 7.19 7.59 7.33 7.35 4.55 6.5Temperature (C) 23.3 24.8 24.6 23.3 23.5 23.5
All of the fish inside of the bowl were still alive after the course of 3 - 4 weeks. this shows that numerous organisms can survive in an isolated area. at the end of the experiment, all 3 of the fish changed colors, probably due to injury inside of the bowl. the water smelt pretty bad and the water wasn't very murky, it was pretty clear. The experiment could have been flawed because when i went to take the readings, the bowl was open so oxygen could have gotten in. Also the fish and plants were always in the light. the plants were always photosynthesizing so there would always be oxygen in the bowl. In real life, it would be in the light and the dark, the plants wouldn't be photosynthesizing 24/7.
